Smooth Finishing with 100, 280, and 2000 Grit Sandpaper

When you need to move from effective surface prep to ultra-smooth polishing, the sanding sequence of 100, 280, and 2000 grit sandpaper is a reliable choice. This combination works across woodworking, automotive refinishing, and resin projects that demand top-quality finishes.

Why This Sequence Works

100 grit efficiently preps surfaces, removing coatings, scratches, or filler marks. 280 grit refines and smooths the surface, preparing it for paint, stain, or sealers. Finally, 2000 grit delivers an ultra-fine polish that creates a glossy, professional look.

Tools You’ll Need

• Orbital sander or sanding block for 100 grit prep
• Sanding sponge or pad for 280 grit refinement
• Foam pad with water spray bottle for 2000 grit wet sanding
• Vacuum and tack cloth

Step-by-Step Process

1. Initial sanding. Start with 100 grit (25-pack) to smooth rough areas and remove old finishes.
2. Refinement. Switch to 280 grit (50-pack) to erase sanding marks and prepare surfaces for coatings.
3. Final polish. Wet sand with 2000 grit (100-pack) for ultra-smooth, glossy results.
4. Clean carefully. Always vacuum and tack cloth between grit stages to ensure a flawless finish.

Special Cases

In woodworking, 280 grit is commonly used before staining, but continuing to 2000 grit provides a luxurious touch. In auto refinishing, 100 grit shapes filler, 280 smooths primer, and 2000 polishes clear coats to mirror-like clarity. Resin projects also benefit from the glass-like smoothness of 2000 grit sanding.

Pro Tips

• Don’t jump directly from 100 to 2000—280 grit is essential for scratch removal.
• Always wet sand with 2000 grit for premium clarity and reduced clogging.
• Use light, even strokes with fine grits to avoid streaks or uneven sanding.

Aftercare

• Apply protective finishes immediately after sanding to preserve smoothness.
• Buff 2000 grit results with compounds for a mirror-like shine.
• Store sandpapers flat and dry to extend their lifespan.

FAQs

• Is 100 grit good for finishing? No, it’s a prep grit—always refine with finer grits.
• Why use 280 grit? It bridges the transition between coarse and fine sanding stages.
• What’s 2000 grit best for? It delivers ultra-fine polishing for resin, auto clear coats, and premium woodworking projects.
